Name characteristics of a contact wound

  • muzzle mark possible
  • soot and powder particles in wound track
  • burning from muzzle flame
  • over bones:
    • stellate entrance wound
    • crater shaped injury in bone


How is the complete wound divided according to shooting range? (4)

  • contact wound (0cm)
  • near contact wound (0-1cm)
  • intermediate range (1-30/50cm)
  • distant (more than 50cm)


How can gunshot wounds be classfied?

  • complete wound
    • perforating
    • penetrating
  • incomplete wound
    • low energy shot
    • graze wound


Name characteristics of a near-contact wound

  • soot
  • flame effect
  • powder particles on skin


What characterises the entry wound?

The elasticity of the skin. The bullet stretches the skin and this is why the wound will be smaller than the caliber


Remember that ...

  • You cannot always connect an entrance wound and an exit wound with a straight line due to tumbling etc
  • when different number of entry and exit wounds are present, you should consider intermediate fragments or fragmentation
  • Shotgun wads (contact/near-contact/intermediate wound) will not be seen in X-ray


Name characteristics of intermediate wounds

powder tatoo


Name characteristics of a distance wound

There is no sooting or soiling on the skin


What to remember during the examination

  • use X-ray or CT to find bullet particles
  • protect the hands of the victim
  • take biopsies from entry and exit wounds
  • never touch the bullets with metal
